Abd al-Aziz bin Rufay' (may Allah have mercy on him) said: I asked Anas bin Malik (may Allah be pleased with him): Tell me something you learned from the Messenger of Allah (peace and blessings be upon him): where did he pray Zuhr on the Day of Tarwiyah? He said: At Mina. I said: And where did he pray Asr on the day of departure? He said: At al-Abtah. Then he said: Do as your rulers do.
